Validations
Validations allow you to ensure users enter correct input values. When you create a validation in Formulate, you are able to indicate a message to be displayed when the validation fails (i.e., when the user types an incorrect value into a field). You can include special placeholders in this message, and they will be dynamically replaced. These placeholders are:
- {name} - The name of the field.
- {alias} - The field alias.
- {label} - The field label.
- {{} - This is an escape sequence in case you want to include a curly brace in your message.
As an example, suppose you had a validation with a message of “This field, {name}, is mandatory”:
If you applied it to the field with a name of “First Name”, the resulting message that would be displayed to the user would be “This field, First Name, is mandatory”:
